Why didnt they get Trouba

They didn't get him because he didn't want to sign with a canadian team.

Because he was not willing to sign a long term deal with a Canadian based team. That’s why.

I mean yeah I saw that but it just sounds like an excuse cause he didn’t like WPG... I mean we do have doctors in Canada too

There's a story out there that Trouba's camp threatened that he'd demand a trade or holdout if he was dealt anywhere but the Rangers and it sounds like there were plenty of teams interested and some offered better deals then the Pionk/1st package the Jets got but Chevy's hand was forced a bit. If I'm understanding it correctly it appears Chevy had better offers given to him but he didn't want to screw over any of his fellow GM's so he traded Trouba to where he wanted to go and I guess that was the best the Rangers would offer cause they knew that's where he wanted to go so they knew they didn't have to give up much. Don't know if that makes any sense but that's how I'm interpreting the stories I've read about it, Pittsburgh was one of the teams that pushed for him and I read about this in insidepittsburghsports.com.

Do you know about Trouba's personal issues with Canada? My guess is no.
Trouba will not sign any extension and definitely not with a Canadian team. As of right now he has not signed one with NYR and I'm going to assume he hits UFA status and picks his destination.

Winnipeg GM had very little bargaining power to even get fair value nevermind trying to win a trade.
